Process for producing olive wine

Abstract

The invention provides a process for producing olive wine. The process comprises the following steps: olive pomace is selected as the main material; the processes of alcoholic fermentation, filtration, sedimentation and blending are carried out; a cold-hot alternation way is adopted to perform the rapid ageing; and then the olive wine is produced through the active carbon filtration. The process adopts juice-extracted olive pomace as the raw material, thereby improving the comprehensive utilization ratio of olive; a polyether sulfone film is adopted for filtering, thereby the loss of alcohol during the filtering process is reduced, and the fermentation yield is improved; the rapid ageing method of cold-hot alternation is adopted to reduce the ageing time threes to six times and improve the production efficiency; the production process is scientific and reasonable, the production time is short and the quality effect of products is good; in addition, devices are lowly demanded, the control is easy, the maneuverability is strong, and the energy consumption is less. The process adopts fruit wine for production, thereby greatly reducing the production cost and being suitable for the large-scale production of olive wine, and the produced olive fruit wine has high clarity, good stability, rich nutrients, good taste and obvious economic benefits.

Description

technical field [0001] The invention belongs to the field of fruit wine processing, and more specifically relates to an olive wine production process.

Problems solved by technology

[0003] Fujian Province is the main producing area of ​​olives. However, due to the relatively concentrated harvesting period of olives, the short time to market, and the high content of polyphenols in the fruit, it is easy to brown and the freshness period is not long, resulting in low economic benefits of olives. , fruit farmers increase production without increasing income, which has a huge impact on the sustainable development of the entire olive industry

At present, olive products are mainly candied fruit, with a single variety, which is not conducive to the development of the olive industry.
